Re: [Paparazzi-devel] V4.9 and BAT value problem

[Eric BAHIER]

Hi felix,

Thanks to look at my bug....
I test with 4 targets:
        Lisa/L 1.0 without alone (no GPS, no IMU.....) just the Xbee
        Lisa/L 1.0 full ready to fly (GPS,IMU,Xbee, Rx)
        Lisa/M 1.0 full ready to fly (GPS,IMU,Xbee, Rx)
        booz ready to fly (GPS,IMU,Xbee, Rx)

On my side I work on a lab PC, actualy in paparazzi V4.0.1... it smell good.
I will verifiy evrything on 4.0.1.... and make the update step by step to try to find when the bug appear, I will send you his birthday.....

Last time I play with GIT with limited updated, it was not complete succesfull.... I will win to GIT!!!



Yesterday I look in source code... batcheker.c.......... I can not see anything.
My feeling is a time schedule problem, I suppose we "forgot" to restart the ADC processing, the ADC value stay the same evrytime after the first read....
Today it is only a idea, a feeling......

many thaks,

Eric

Hi Eric,

it works on my Lisa/L 1.0 (no IMU connected at the moment).

I tested it on the Lisa/M 1.0 as well and it indeed doesn't work correctly, and it seems that there is some problem with proper adc setup if other peripherals are used as well.

It works when adding adc_init(); electrical_init(); to the end of main_init()...

The test_adc target works fine.

Couldn't find the actual problem yet... Stephen, Esden, any ideas/time to look into this?

Created an issue for it: https://github.com/paparazzi/paparazzi/issues/339

Cheers, Felix

Hi,

I try to kill my bug of BAT value on GCS.... it stil alive.....

I have 2 problems,
    To have a good value (8V) I need to modify the adc value.....with the documented function

 <section  name="BAT">
    ...
    <define  name="VOLTAGE_ADC_A"  value="0.011"/>
    <define  name="VOLTAGE_ADC_B"  value="0.635"/>
    <define  name="VoltageOfAdc(adc)"  value ="(VOLTAGE_ADC_A * adc + VOLTAGE_ADC_B)"/>
  </section>

With this my first mistake is solve (or work around.... perhaps it is a visible part of th iceberg....)

My real bug (I can not find any solution or work arround)

The BAT value is correctly read at power up, GCS give the good infomation (if I use VoltageOfAdc...), Message windows give also the good value.
If the BAT value change (LAB power supply can do it  easly), the GCS an Message value still th power up value... In Message windows the message is updated, but with the power-up value....


This morning I have take My LISA/M, I have used the standard fraser.....xml, I have juste change the IMU to my version, and comment the prog mode to use the standard jtag interface.

This mornig I have updated my config (git pull, make clean, make) My paparazzi version v4.9_devel-337-g34b46d2-dirty.

Anyone I have any idea where I have make the mistake......


Many thanks,

Eric
